* src/cmp.c (bytes): Use INTMAX_MAX, not -1, for “infinity”.
This simplifies the code and is not a value that can be exhausted
these days.
(main, cmp): Treat very large -n values as “infinity”.
* tests/cmp: Test this.
* NEWS: Document this.
* src/cmp.c (specify_ignore_initial):
If the value exceeds TYPE_MAXIMUM (off_t), set the correspnding
ignore_initial value to -1 instead of reporting an error.
(main, cmp, file_position): All uses changed. Hence a huge value
will always do the right thing with regular files, which cannot
contain more than TYPE_MAXIMUM (off_t) bytes. There still may be
EOVERFLOW failures reported for non-regular files, though, as
these can be larger.
* tests/cmp: Test cmp -i N when N cannot fit into 64 bits.
Run "make update-copyright" and then...
* gnulib: Update to latest with copyright year adjusted.
* tests/init.sh: Sync with gnulib to pick up copyright year.
* bootstrap: Likewise.

This improves on yesterday's change, following up on a
remark by Jim Meyering (Bug#22816#21).
* doc/diffutils.texi (Invoking cmp, cmp Options): Follow POSIX more
closely in the documentation of the information appended to the EOF
diagnostic.
* src/cmp.c (cmp): Be more specific about the shorter file's length
and fix some off-by-1 issues in reporting line counts.
* tests/cmp: Adjust to match new behavior.
Don't assume internal details about stdio buffering.
